SM Table 2C and N Litter Pool Partitioning Parameters PC and PN, I.E. the Fraction of Total

SM Table 2C and N litter pool partitioning parameters PC and PN, i.e. the fraction of total C and N in the rapidly decomposing pool estimated by: measured as neutral detergent soluble C or N (NDS), kinetically-defined or optimized against mineralization data (OPT),or simple-linear (SLSCD), multiple-linear (MLSCD) and PLS regression (PLSNIR) models predicting the kinetically-defined litter pool partitioning. The regression models were based upon stepwise chemical digestion (SCD) or near infrared reflectance spectroscopy (NIR) data. For validation ‘OPT’ see main Table 1.
